Hybrid Decoder Pools
Hybrid decoder pools ensure that the correct hybrid decoder is used in environments with more
than one matrix switch or in environments in which specific hybrid decoders are assigned to a
group of keyboards. Figure 25 shows an environment with four CCTV keyboards and monitors but
only three hybrid decoders. Ideally, a hybrid decoder is available for each keyboard to ensure that
all operators can perform playback features simultaneously.
In this example, ISP_1 is assigned to work exclusively with hybrid decoder 10. Because both
devices have been assigned to pool #1, HyDec10 is available exclusively for that keyboard for
playback requests.
The two other hybrid decoders in pool #2 are shared among the remaining three operators, making
playback features available only to the first two requests. Hybrid decoders that are in use become
available to the pool as soon as an operator stops the playback request or the playback timeout
occurs. Figure 20 on Page 5-1 shows how to change the default playback timeout of 36000
seconds.
